I am reopening this as this still does not work for me. It works for removable media but not for built in devices. If you prefer you can close this again and I will create a different bug for the specific case of HDs. Here is some more data:

I think it should be a separate ticket, but for the record, mounting previously mounted disks is working with my systems since ages. Could it be something ext2 specific? For me it works with BFS disks (read-only<->read/write status is restored also) and ReiserFS.

I would have preferred a new bug, but since we're already here... :-)
The original bug description is somewhat vague anyway, so it probably still fits, and might even have had similar reasons (beyond the missing notifications).

As I said, it works fine over here; I will see that I get an ext2/FAT drive in my computer to see if I can reproduce it.

Yes, with BFS it does work here too, but not with FAT or EXT2. I do not have any ReiserFS partitions to check. Anyway, I would expect this to be more generic and not FS dependent so I am pretty sure there is a bug somewhere.

Did some more tests. it seems to work for some file systems and not for others and this does not seem to make much sense. In any case, it works with NTFS and BFS (of course), but not with fat or ext2 partitions.

This may be fixed in hrev30720. The automounter was using the wrong mount mode for removable media during the initial scan. I am not quite sure if your specific case is what I fixed along the way by fixing a couple of other problems, but please re-test in any case.

@Bruno - With hrev52025 x86_64, I tested this for another ticket and I have normally working automounts for either audio/data CDs and NTFS/exFAT/FAT USB drives. So from the original purpose of this ticket, I'd say the ticket is resolved on my end for CD/DVD auto mounting.
